OT: Modernish PC and USB questions with a Mac twist

This is semi-ontopic since I'm building the system to emulate a PDP-10. Anyway I just got a pair of Intel D810EMO motherboards for free. I plan to add a DIMM, CPU, small HD, and a PS. Probably won't even bother with a case as I'd like to save space. Anyway, it's been a long time since I had much to do with PC's I've got the following questions. Is a Pentium III 800EB and a 800B processor the same thing? Can a Mac USB keyboard (from my G4/450) be used on a PC? Zane -- | Zane H.
